Definitions

  • the object of the present invention is a floating platform for harnessing wind energy incorporating notable innovations and advantages over the techniques used so far.
  • the invention proposes the development of a floating platform for harnessing wind energy which, because of its particular arrangement, allows for a highly significant reduction of costs with respect to the prototypes currently under development, and which could better be used because of its reduced draft, both in shallow and in deep waters, and it can also be manufactured and transported very easily.
  • Harnessing wind energy for generating electric energy by means of wind turbines the development of which has been a high priority in recent years mainly by means of land-based wind farms, is known in the current state of the art.
  • Tensioned mooring lines fix the platform to the seabed and practically immobilize it, thus achieving stability.
  • the disadvantage of this type of stabilization lies in the fact that it requires auxiliary flotation systems during transportation and involves complex operations for positioning and fixing the platforms to the seabed, in addition to the steep costs associated with the installation.
  • These platforms are characterised by having a reduced surface on the water plane area in order to reduce the action of the waves on the platform and the corresponding movements produced as a result thereof, the floating elements being practically submerged once positioned at the site, and they also have a strong ballast to lower the position of the center of gravity thus achieving proper stability.
  • the simplest type of this group is made up of a single vertical cylindrical flotation element of great length, the wind turbine being located on its upper part and with the ballast in its lower part in order to lower the position of the center of gravity, as in the SPAR buoys.
  • the HYWIND design by STATOIL is a representative example, there existing other patents with identical types, such as WO 2010/106208 and WO 2013/093160.
  • Patent WO 2012/13116 is a variant, which has a horizontal cantilever element on the lower part of the floating vertical cylinder, and the anchoring system fixed to the end thereof, enabling it to be oriented with the wind.
  • Semi-submersible platforms can also be included in this group, since they have a reduced surface on the water plane area, corresponding to the vertical columns that support the wind turbine, the greater part of the floating elements generally being submerged.
  • Stability is achieved by distancing the columns in order to increase the metacentric height, and by using additional ballast in order to position the center of gravity below the metacentre.
  • Patent US 2012/0103244 corresponds to a semi-submersible platform with four vertical buoyant columns, three of which are arranged on the vertices of an equilateral triangle and the fourth in the center, which supports the tower of the wind turbine.
  • Patent WO 2002/10589 presents a type of semi-submersible platform with a central flotation chamber and a tensioned vertical anchoring cable, which is also central, in addition to an additional system of anchoring lines, so it can be classified as a combination of semi-submersible and stabilised by tensioned anchoring lines type platform.
  • patent US 2011/0155038 proposes a platform type with three or more floating vertical cylinders, joined to the seabed by tensioned cables.
  • Pillbox type floaters with a square or circular horizontal cross section, or those corresponding to patent JP2004251139, with a monohull floater in the form of an O-ring, are suitable for this approach.
  • the barges are positioned through moorings to a fixed point, able to rotate around the same, like a weather vane, in order to align with the wind, in which case they would receive the action of the waves and the wind preferably in one direction, which is why it is worth considering configurations with inertial and response characteristics that are very different depending on the main horizontal longitudinal axis of alignment and the perpendicular alignment to the same on the horizontal plane.
  • the present invention contributes to solving the current problem with a specific type of platform for harnessing wind energy and its corresponding anchoring system, which allows for a simple, practical and affordable construction, installation, use and maintenance thereof.
  • the present invention has been developed with the aim of providing a floating platform for harnessing wind energy, of the type that uses a wind turbine for generating energy, and which falls within the group of offshore platforms that obtain stability entirely by floatation, the positioning of which is carried out through mooring to a fixed point, around which the platform can rotate in order to align with the wind.
  • This platform is of the type described in the pre-characterising part of Claim 1 , comprising a tower with a wind turbine, two horizontal, identical cylindrical floating elements parallel to the main longitudinal axis of alignment, the tower and the floating elements being interconnected by bar structures.
  • the floating elements are joined to a stabilising element beneath the floating elements.
  • the main problem facing platforms stabilised by flotation is achieving a geometry, which, along with having acceptable stability, also achieves its own periods sufficiently distant from the periods of incident swell.
  • the invention proposes the combination of a twin hull platform, with two horizontal, identical cylindrical floating elements with an ovoid cross section and which are closed at their ends, thereby allowing for greater transverse stability with respect to a monohull solution with the same flotation surface, and with a submerged stabilising element which has characteristics aimed at reducing wave-induced movements as much as possible and drastically reducing the draft of the platform.
  • the aforementioned stabilising element is substantially flat, it is situated beneath the floating elements and comprises two substantially rectangular first concrete slabs, either solid or more lightweight, with a ribbed structure, arranged perpendicularly to the axes of the floaters and joined to said floaters by means of auxiliary structures, coplanar with said first concrete slabs.
  • Said stabilising element enables to greatly increase the pitch period of the platform, partly due to the inertia of the mass of the slabs and partly due to the inertia of the added hydrodynamic mass associated therewith.
  • the stabilising element may comprise two second substantially rectangular concrete slabs arranged parallel to the axes of the floaters at their outer lower part and joined to them by means of auxiliary structures that would limit the aforementioned movements in the same way.
  • both the floating and the stabilising elements are made of reinforced or prestressed concrete.
  • Concrete structures have the aforementioned problem of heavy weight, extremely low tensile strength or the presence of cracks due to intense bending stress.
  • the problem of excess weight is not serious, given that with the developed configuration, the centre of gravity can be lowered and positioned well below the metacentre, which largely increases stability, while at the same time maintaining a reduced draft because they are hollow floaters with relatively thin walls.
  • the floating elements have an ovoid cross section and are closed at their ends by a convex form. This geometry causes that when the floating elements are subjected to hydrostatic pressure they compress, such that the concrete that forms part of the same works by compression and prevents it from cracking. Moreover, in order to further ensure said compression of the cylinders, they are subjected to pre-compression, using the technique of prestressed concrete, while at the same time they are compartmentalised and internally stiffened by transverse partitions or bulkheads.
  • the assembly of bars is made of reinforced or prestressed concrete.
  • the assembly of bars is made of steel.
  • the assembly of bars is made of a mixture of steel and concrete.
  • the floating platform incorporates a buoy, said buoy being provided with anchoring means on the seabed comprising at least three mooring lines with their corresponding anchors and/or concrete blocks and/or piles for fastening to the seabed, as well as electrically transmitted rotating means comprising a swivel connector positioned on the buoy itself or on the platform and a cable, the cable coming from the seabed and reaching the platform itself, and rotating means for mooring, comprising a swivel joint to which the moorings of the platform are joined.
  • anchoring means on the seabed comprising at least three mooring lines with their corresponding anchors and/or concrete blocks and/or piles for fastening to the seabed, as well as electrically transmitted rotating means comprising a swivel connector positioned on the buoy itself or on the platform and a cable, the cable coming from the seabed and reaching the platform itself, and rotating means for mooring, comprising a swivel joint to which the moorings of the platform are joined.
  • the explained arrangement allows for the rotation of the platform of the invention around the buoy in order to align itself with the wind, like a weather vane, which allows the longitudinal oscillations of pitching and the transversal oscillations of rocking to be treated as separate phenomena and be optimised depending on their impact on the operation of the wind turbine.
  • the construction of a platform for harnessing wind energy positioned in and adapted to a marine environment is made simple, practical, affordable and effective.
  • the platform of the invention provides an unprecedented solution that satisfactorily solves all of the aforementioned problems, obtaining a specific type of floating platform for harnessing wind energy that meets the requirements of a reduced draft, as well as that of stability and wave-induced movements that are suitable for the wind turbine and its tower, both in normal environmental operating conditions and in extreme environmental conditions, and all at a reduced cost.
